rear suspension on 71super....

[Piledriver]

Having the ass end swing around is great... Intentionally, on an AUTO-X course.

I've been ~backwards at ~50MPH, going seeply downhill on a gravel road with a cliff on one side and a near vertical hill on the other...
with plenty of nice big trees, ready to catch me... bla bla bla.

SOMEHOW (someone MUST look after idiots) I reeled it in. I don't know how, nor do I EVER wish to recreate the situation to find out.
(IIRC I was 15 at the time, just got my license.)

Understeer is a good thing. Most folks are MUCH faster around a race course wit a little vs oversteer.
It usually has to be carefully built INTO a Bug due to the weight bias.

Do the rear bar last. It's easy, not expensive, and potentially lethal.
